PRIORITY

0001This application claims the benefit of priority to U.S. Provisional Application No. 63/175,475, filed Apr. 15, 2021, which is incorporated by reference in its entirety into this application.

BACKGROUND

0002Readily accessing a blood vessel can require multiple sticks to access the correct blood vessel. Clinicians may use vein visualizers, medical devices that detect subcutaneous blood vessels and project a depiction of the vein topography on the skin surface, to readily access the correct blood vessel. Vein visualizers must be held some distance away from the skin surface where hands or other medical devices may disturb the depiction of the vein topography, adding difficulty to accessing the correct blood vessel. It would be beneficial to clinicians and patients to have a vein visualizer whose depiction would not be disturbed, allowing clinicians ready access to the correct blood vessel. Disclosed herein are an ultrasound imaging system and method of use that address the foregoing.
